The invention discloses a suspended reservoir which comprises a reservoir body and is characterized in that the reservoir body is of a small-sized reservoir body, a medium-sized reservoir body or a large-sized reservoir body, wherein the small-sized reservoir body, the medium-sized reservoir body or the large-sized reservoir body is a sealed reservoir body, and the sealed reservoir body comprises a water inlet and a water outlet; and the water outlet is connected with a valve, further connected with an industrial and agricultural water supply pipe, simultaneously externally connected with a water purifier and further connected with a domestic water supply pipe. The small-sized reservoir body or the medium-sized reservoir body is supported in the air by adopting support legs or support columns, the large-sized reservoir body is built by adopting masonry cement, and the reservoir body is built in the position with higher relief or the high position of a hillside capable of receiving river, watercourse, stream or surface running water and supported through a highland and a cornerstone. The structure of the suspended reservoir is simple and practicable, low in construction cost and high in safety coefficient. The construction of the reservoir is not affected by non-uniform distribution of geographical and earth water resources and the like, and the reservoir can be constructed in any place with rainwater around the world. Simultaneously, three inventions, namely an aerial water receiving canopy, the suspended reservoir and a suspended reservoir power generation station can be combined, thereby fully generating power to provide the power to people for production and living.
